Volatilization Mechanism of Group Elements in Ti6Al4V During Electron Beam Cold Hearth Melting
Ti6Al4V alloy is a widely used titanium alloy. During the vacuum smelting of Ti6Al4V alloys, the Al is highly volatile, which leads to the difficulties in the control of alloy composition. Thus, studying the compositional volatile mechanism of the alloy is of significance. In this work, the infinite...

| description | Ti6Al4V alloy is a widely used titanium alloy. During the vacuum smelting of Ti6Al4V alloys, the Al is highly volatile, which leads to the difficulties in the control of alloy composition. Thus, studying the compositional volatile mechanism of the alloy is of significance. In this work, the infinite dilution coefficients of Ti6Al4V are calculated by the α-function method. The activity coefficient is predicted by the molecular interaction volume model. The Langmuir formula is modified to predict the alloying of Ti6Al4V. When the average temperature of the bath is 2050 K, the content of V in Ti6Al4V is 4%, and the proportion of Al in the alloy is
